Inclusive Info Hub

An estimated four million people in India alone live with cerebral palsy and other conditions that make speech difficult or impossible, and for most of them, Western speech generating devices priced in the thousands of dollars were never a realistic option. At Inclusive Info Hub, every AAC app reviewed here is measured against one honest question: does it give a nonverbal user independence, or does it just give a wealthier family independence. In 2026, Avaz AAC entered a new chapter entirely, announcing it will work closely with PRC-Saltillo, the company behind TouchChat and one of the most established names in AAC hardware, to build shared reach across both platforms.

Picture a mother in Lahore, sitting on the floor with her nonverbal son, trying app after app that spoke only in American English, priced in dollars that did not stretch the way rupees needed to. She finally lands on Avaz, built in Chennai specifically because its founder watched Indian children with autism struggle to find a voice in a market built entirely for someone else's country. Her son taps his first symbol. He does not need to become fluent in a foreign vocabulary set to be understood. He just needs to be himself.

That is what Avaz was built to fix from day one. This is where that story starts.

The Story Behind Avaz

Avaz was invented by Ajit Narayanan, an engineer who returned to India in 2007 and began volunteering at special education schools in Chennai. Working closely with Vidya Sagar, an organization serving children with special needs, Narayanan launched Avaz in 2010 as India's first augmentative and alternative communication app, built specifically to help children with autism and other complex communication needs bridge the gap between abstract language and the pictures they could already understand.

The name itself means "voice" in Persian, a deliberate choice for an app built around giving nonverbal users exactly that. The mission behind it was never just accessibility for its own sake. Narayanan has spoken about wanting Avaz to do more than let a child point at a picture of a cookie, aiming instead to teach the underlying structure of language so users could eventually build full, flexible sentences rather than memorized phrases.

The app's early recognition came quickly. In 2010, Narayanan received India's National Award for the Empowerment of Persons with Disabilities. In 2011, MIT Technology Review named him a global innovator and later included him on its TR35 list, recognizing Avaz alongside some of the most significant technology innovations of that era. The Tamil Nadu state government went on to purchase iPads loaded with Avaz for a pilot program in participating schools, one of the first government backed AAC deployments of its kind in India.

By 2026, Avaz had grown well beyond its original single app, expanding into a global platform used across school districts, therapy centers, and homes in multiple countries. The company's announced collaboration with PRC-Saltillo, the maker of TouchChat covered elsewhere on this blog, signals a new phase where two AAC companies with very different origin stories, one built in Silicon Valley and Chennai for affordability and regional language reach, the other built in the United States around decades of clinical AAC hardware experience, begin working toward shared infrastructure rather than competing in isolation.

Platform Clarification — Both Stores Confirmed

Apple App Store: Search "Avaz AAC" for the subscription version, or "Avaz AAC - Lifetime Edition" for the one time purchase version, both published by Avaz Inc.

Google Play Store: Search "Avaz AAC," published by Avaz Inc. An India-specific listing, "Avaz AAC India," is also available with localized pricing and Indian language defaults.

Website: avazapp.com for institutional licensing, teletherapy information, and language availability details.

The app works identically across iOS and Android, and both platforms receive the same feature updates on the same release schedule.

What Avaz Actually Does

Avaz is a picture and text based AAC app that converts taps on symbols into spoken sentences using a research based vocabulary structure. Roughly 80 percent of everyday speech is made up of a relatively small set of core words, and Avaz organizes its vocabulary around that principle, placing high frequency words in consistent, predictable positions so users build motor memory over time rather than hunting through menus for every phrase.

The vocabulary library includes more than 40,000 SymbolStix pictures, giving therapists and parents an enormous range to build out a user's personal communication board without needing custom artwork for every new word. Predictive text and a keyboard mode sit alongside the picture based system for users who are ready to move toward more text driven communication.

Key Features in Full Detail

Core Word Vocabulary Structure

Rather than teaching isolated nouns like "cookie" or "ball," Avaz's vocabulary is arranged around core words like "want," "more," and "stop" that appear across nearly every sentence a person might build. This mirrors how speech and language therapists actually teach AAC, aiming for genuine sentence construction rather than a system that only ever produces requests.

Indian and International Language Support

Avaz's India-specific edition supports six Indian languages including Hindi, Tamil, Telugu, Kannada, Malayalam, and Marathi, with additional personalization available for Gujarati and Bengali. The broader international version adds French, Danish, Swedish, Hungarian, Faroese, Vietnamese, and Bengali as default bilingual offerings, a language list that continues to grow with each yearly update.

Cloud Backup Across Platforms

Vocabulary progress can be backed up to Google Drive, Dropbox, or iCloud at a customizable interval, meaning a family switching a child from a school Android tablet to a home iPad does not lose months of personalized vocabulary work in the transition.

Visual Themes Including Dark Mode

Avaz includes Classic Light, Classic Dark with high contrast, and a dedicated dark mode called Outer Space. The dark theme has proven particularly useful for adult AAC users and for anyone using Avaz alongside eye tracking hardware, where screen glare can interfere with tracking accuracy.

Touch Accommodations for Motor Differences

Settings like Select on Release, adjustable hold duration, and Ignore Repeat let therapists tune how the touchscreen responds to a specific user's motor control, reducing accidental selections for users with limited fine motor precision.

Free 14-Day Trial Without a Credit Card

Families can test the full feature set for 14 days before being asked for any payment information at all, which matters enormously for a purchase this significant for a household's communication needs.

Pricing — Complete and Honest

International Pricing: Avaz AAC subscription pricing runs at $9.99 per month, $99.99 per year, or $199.99 as a one time lifetime purchase through the Lifetime Edition. Educational institutions purchasing 20 or more licenses receive a 50 percent discount.

India-Specific Pricing: The Avaz AAC India listing offers substantially reduced local pricing, with a monthly subscription around Rs. 299 and an annual plan around Rs. 2,999, reflecting purchasing power in the Indian market specifically rather than a flat global dollar price.

It is worth being direct about something we found in researching this review: some users have reported inconsistent lifetime pricing between accounts, with one person quoted a lifetime price notably higher than what a friend was quoted at the same time. This kind of pricing inconsistency is a real frustration worth knowing about before you commit to the lifetime tier, and we would recommend confirming the current price directly in the app before purchasing.

Who Avaz Is Built For

Nonverbal and Minimally Verbal Children With Autism or Cerebral Palsy

The core word vocabulary structure and extensive symbol library are built around progressive language development, taking a user from single word requests toward full sentence construction over time rather than freezing them at a basic request level indefinitely.

Families and Therapists Across South Asia

The India-specific language support and regional pricing tier make Avaz one of the only AAC apps genuinely built around South Asian affordability and language needs rather than adapting a Western product after the fact.

School Districts Running BYOD or Mixed-Device Programs

Because Avaz runs identically on Android and iOS with cross platform cloud backup, schools with a mix of student owned devices and school issued tablets can standardize on one AAC app without forcing a single hardware choice.

Adult AAC Users, Including Those Using Eye Tracking Hardware

The dark mode theme and touch accommodation settings were specifically noted as helpful for adult users and those relying on assistive input hardware beyond simple touch, a group that AAC apps built primarily around pediatric use sometimes overlook.

Avaz vs Proloquo2Go — The Practical Comparison

Both apps are built around research based vocabulary structures and serve overlapping populations, but the differences matter for a real purchasing decision.

Proloquo2Go is iOS only, has a longer clinical track record in the United States and other Tier 1 markets, and costs $249.99 as a single one time purchase with no subscription option at all.

Avaz is available on both iOS and Android, offers flexible monthly, yearly, and lifetime pricing, includes India-specific regional pricing and language support that Proloquo2Go does not offer, and is now moving toward deeper collaboration with PRC-Saltillo's clinical AAC ecosystem.

For families needing Android compatibility or Indian language and regional pricing, Avaz is the clearer fit. For clinics and schools already standardized entirely on iOS with an established Proloquo2Go workflow, switching may not be worth the disruption.

Honest Limitations

Urdu is still not supported. Despite genuinely strong South Asian language coverage, Urdu is notably absent from both the international and India-specific language lists, a real gap for Pakistani families who would otherwise be an obvious fit for this app.

Some features are region locked. At least one Android user has reported that certain vocabulary and grid customization features remain locked to the US language setting even when using the app from another country, which can be frustrating for international users expecting full feature parity.

Subscription pricing has created real access complaints. Several long time users who relied on an earlier, more fully free version of Avaz have expressed frustration in App Store reviews about the shift toward paid subscriptions, noting that families without steady income are the ones most likely to be priced out of a tool they may need most.

Lifetime pricing has shown inconsistency between accounts. As noted above, at least one user reported being quoted a different lifetime price than a friend purchasing around the same time, which is worth double checking directly in the app before paying.

Who founded Avaz and why? Ajit Narayanan founded Avaz in 2010 in Chennai after volunteering with children with special needs, aiming to build an AAC app that was both affordable and built around Indian languages rather than adapted from a Western product.

What This Means for Users in Pakistan and Across Asia

Avaz remains one of the most South Asia relevant AAC apps available, even without Urdu support. A family in Lahore or Islamabad researching AAC options will find an app genuinely built with regional affordability in mind, though they should expect to build custom Urdu vocabulary manually rather than relying on a native language pack. Families in India benefit from dramatically reduced local pricing that is not available to neighboring countries, which is worth knowing upfront so Pakistani families are not caught off guard by higher international pricing tiers when comparing notes with Indian AAC communities online.

The 2026 PRC-Saltillo collaboration is worth watching closely for South Asian families in particular. If it eventually leads to regional language expansion or shared vocabulary resources between the two platforms, it could meaningfully close the Urdu gap that currently limits Avaz's usefulness for Pakistani households specifically.

A Closing Thought

Ajit Narayanan did not set out to build a business. He set out to answer a specific, local problem: Indian children with complex communication needs deserved a voice in their own languages, at a price their families could actually afford. Sixteen years and a partnership with one of AAC's biggest global names later, that original problem is still the thing driving the product forward.

The mother in Lahore watching her son tap his first symbol did not need Avaz to be perfect. She needed it to sound like his world, not someone else's. For millions of families across South Asia, that is still the whole point.
